Title: Surface treatment of piston rod
Inventor: OZAWA MAYUMI
IPC: C25D7/00
Filed: 1992-05-13
Abstract: PURPOSE:To surely prevent the generation of rust on a bare surface in a piston rod the surface of which is plated with hard chromium by grinding before plating and finishing by polishing after plating and baking. CONSTITUTION:For example, the bare surface of the piston rod is buff ground to form 0.2-0.6mum fine ruggedness and hard chromium plated after etching treated. Thus, a hard chromium plated film free from pinholes or the like is obtained. Next, the piston rod is heated at 180 deg.C and is baked after allowed to stand in the atmosphere for 5 hours. Thus, occluded hydrogen in the plated layer is released and the crack of the base material caused by brittle hardening caused by the large quantity of occluded hydrogen is prevented. After that, the hard chromium plated layer is finished by buff polishing to form a plastic fluidized layer having >=0.2mum depth on the surface.

Title: Seaweed lectin and its manufacture
Inventor: MURAMATSU KIYOSHI
IPC: B01D15/08
Filed: 1995-05-23
Abstract: PURPOSE: To obtain a novel seaweed lectin having characteristic agglutination activity and a specific sugar binding specificity by extracting the lectin from algae of Geldium amansii genus. CONSTITUTION: A seaweed lectin is extracted from algae of Geldium amansii genus by dipping the algae in a water-based medium prepared by adding a phosphate buffer to a physiological saline for about 12-24 hours at a temperature of 4-25 deg.C. The extracted solution is subjected to affinity chromatography using a chitin column and the adsorption fraction is eluted with 50-100mM NH4 OH, separated, and refined. The obtained lectin shows strong agglutination activity against the Group O human, rabbit, and rat red blood cells, but the agglutination disappears or decreases when the red blood cells are treated with pronase. In addition, the lectin does not show any agglutination activity against Group A and B human and sheep red blood cells. Moreover, the lectin strongly labels N-acetylchitotetraose, fetuin, asialofetuin, etc., and has a specific sugar binding property.

Title: Production of probe
Inventor: OGAWA KENICHI
IPC: C25F3/16
Filed: 1987-06-15
Abstract: PURPOSE:To produce a probe having an extremely sharp tip with good productivity by masking the specific part of a probe material under an electrolyte surface and energizing said material as an anode at the time of producing the probe having the sharp tip by electrolytic etching. CONSTITUTION:A single crystal of W, Pt, Ta, TiC, etc. or a polycrystal material 4 thereof as the probe material provided in an electrolytic cell 1 is masked with a masking material 5 such as resist ink except the tip forming part below the electrolyte surface and a DC current is passed or AC or superposed AC-DC current is passed between the probe material as the anode and a counter electrode 3 to effect an electrolytic treatment. An aq. KCN soln. is used as the electrolyte 2 if the probe material is Pt and an HF-H2SO4 soln. is used if said material is Ta or TiC. An electrolytic etching reaction takes place concentrically in the electrolyte surface part of the non-masked part of the probe material and the dissolution progresses around this part until finally the probe material is cut and the probe having the sharp tip falls into the electrolyte. Said probe is, therefore, pulled from the electrolyte and the masking material is removed therefrom. The probe is thus produced.

Title: Variable block length packet exchange system
Inventor: NAGAI MASAHIRO
IPC: H04M3/00
Filed: 1986-06-24
Abstract: PURPOSE:To efficiently attain multiple access traffic packet exchange where packets with different block lengths exist by providing a field representing a data block length in a call packet. CONSTITUTION:A terminal equipment, in making a call, sets a block length of a data to be transferred at present as the data block length of a call packet and makes a call to a network (packet exchange). The packet exchange stores the data block length of the call packet into a memory corresponding to the logic channel. The normality of the call packet is checked by the network, and when it is normal, an incoming packet is sent to an opposite terminal equipment. A called terminal equipment, when incoming call is to be accepted, sends a call acceptance packet to the network, and the network, in receiving the call acceptance packet, sends a connection end packet to the caller terminal equipment to complete the connection. Then a data packet is transferred and the packet exchange discriminates the logic channel number of the received data packet and reserves a packet buffer while looking for the data block length stored in the memory to the logic channel number.
